What is the speed of sound in the air at a temperature of 20 C?
343m/s
If the temperature is TC=20°C(T=293K), T C = 20 ° C ( T = 293 K ) , the speed of sound is v=343m/s. v = 343 m/s .
What is the speed of sound in water?
about 1,480 meters per second
Sound travels faster in water than in air. The speed of sound in air under typical conditions is about 343 meters per second, while the speed of sound in water is about 1,480 meters per second. Fundamentally, standard sound is a compression wave traveling though a material.
What’s the speed of a sound wave through water at 25 C?
1496 m/s

How do you measure the speed of sound in water?
A sound velocity probe is a device that is used for measuring the speed of sound, specifically in the water column, for oceanographic and hydrographic research purposes.
How does temperature affect the speed of sound in water?
Warmer water allows sound to travel faster. Sound travels a bit faster in warm water than it does in cold. Keeping salinity and pressure constant, sound travels about 15 feet per second faster for every 1.8 degree Fahrenheit rise in temperature.
How is the temperature affect the speed of sound in water?
The speed of sound in water increases with increasing water temperature, increasing salinity and increasing pressure (depth). The approximate change in the speed of sound with a change in each property is: Temperature 1°C = 4.0 m/s.
How is sound measured in water?
Sound in water is measured using a hydrophone, which is the underwater equivalent of a microphone. A hydrophone measures pressure fluctuations, and these are usually converted to sound pressure level (SPL), which is a logarithmic measure of the mean square acoustic pressure.
What is the speed of sound in water at 0 C?
about 331 m/s
At 0 °C (32 °F), the speed of sound is about 331 m/s (1,086 ft/s; 1,192 km/h; 740 mph; 643 kn).
What is the speed of sound in distilled water at 25 C in m s?
1450 to 1498 meters per second
Sound waves tend to travel faster at higher temperatures. They range from 1450 to 1498 meters per second in distilled water and 1531 m/s in seawater at room temperatures (20 to 25 °C).
How do you find speed of sound with temperature?
If the temperature is TC = 20 °C (T = 293 K), the speed of sound is v = 343 m/s. The equation for the speed of sound in air v = √γRTM can be simplified to give the equation for the speed of sound in air as a function of absolute temperature: v=√γRTM=√γRTM(273K273K)=√(273K)γRM√T273K≈331m/s√T273K. v=fλ.
How is the speed of sound calculated?
Sound Speed in Gases the speed of sound is vsound = m/s = ft/s = mi/hr. For the specific example of dry air at 20°C, the speed of sound in air is 343 m/s, while the rms speed of air molecules is 502 m/s using a mean mass of air molecules of 29 amu.
Why is the speed of sound faster in water?
Sound waves travel faster in denser substances because neighboring particles will more easily bump into one another. Take water, for example. There are about 800 times more particles in a bottle of water than there are in the same bottle filled with air. Thus sound waves travel much faster in water than they do in air.
